Abstract: Embodiments of this application provide a cross-chain transaction method and apparatus. The cross-chain transaction method includes determining, by a first node, that a first transaction status of a first transaction is a first status, the first status indicating that consensus verification on the transaction succeeded, the first node maintaining a first blockchain and the first transaction belonging to the first blockchain. The method includes obtaining, by the first node, a second transaction status of a second transaction, a second node maintaining a second blockchain and the second transaction belonging to the second blockchain. The method includes modifying, by the first node, target data, the modifying being based on first transaction data of the first transaction when the second transaction status of the second transaction is the first status, the target data comprising data in a state machine of the first node, the target data being related to the first transaction.

Abstract: This invention provides a kind of fuel filler cap actuator and automotive vehicle, comprising screw shaft, rotor, housing, first reset spring, lock block and lock block driving device; Under the action of the lock block driving device, the lock block can be rotated between the locking angle and the unlocking angle; the lock block driving device adopts an electromagnetic drive method to drive the lock block. This avoids the use of a motor drive, and achieves locking/unlocking of the fuel filler cap through the mutual interaction of the first and second magnet, which significantly reduce operational costs and increase life expectancy.

Abstract: Disclosed is an alignment device for a fiber ferrule comprises: a ferrule holding part configured to hold the fiber ferrule in a manner that the fiber ferrule is rotatable about its central axis; a ferrule rotating part configured to rotate the ferrule about the central axis by a predetermined angle; and a marking part configured to mark on an outer surface of the ferrule rotated by the predetermined angle. Also disclosed is a fiber alignment machine comprises the above alignment device and a first ferrule grip device gripping a ferrule out of a ferrule clamp and then moving the ferrule to a ferrule holding part. The present invention also relates to a fiber alignment method comprising holding a ferrule in a ferrule holding part in a vertical direction; rotating the ferrule about a central axis thereof by a predetermined angle; and marking on an outer surface the ferrule rotated by the predetermined angle.

Abstract: A vacuum melting furnace for infrared glass, includes an upper furnace body and a lower furnace body that can be connected with each other or isolated from each other. Vacuum melting of the infrared glass is achieved in the upper furnace body wherein the influence of water in the environment is eliminated. The vacuum negative pressure environments can promote separation of hydroxyl in the structure, which achieves removing of hydroxyl in the glass, and then discharging of the molten infrared glass is conducted at atmospheric pressure in the lower furnace body. By using the vacuum melting furnace for infrared glass, infrared glass with good spectrum transmission performance can be obtained with improved property stability and optical homogeneity, which facilitates the preparation and molding of large sized and special-shaped infrared glass products.
